Roof edge construction

Abstract

An improved roof edge structure of the type providing a gravel stop and a water dam around the periphery of a roof deck is described. The roof edge structure features a novel cant securing assembly which includes a cant member and a retainer member. The cant member has a flange portion adapted for flush surface engagement with a top surface of the roof deck, an inclined sheet portion sloping upwardly from the flange portion generally toward the edge of the roof deck, and a generally vertical sheet portion turned downwardly from the inclined sheet portion. The retainer member is adapted to be fastened to the top surface of the roof deck and has a securing means for confining the movement of at least the vertical sheet portion of the cant member.
